Figure 3. Ethanol-induced triglyceride (TG) accumulation is mediated through lipin-1 induction in AML-12 hepatocytes.
(A) AML-12 cells were treated with ethanol (100 mM) or inhibitors, 4-methylpyrazole (4-MP) and cyanamide (Cya), for 48 h and cellular TG levels were measured. (B) AML-12 cells were transfected with control siRNA or Lpin1siRNA. Forty-eight hours after transfection, ethanol (E; 100 mM) was added. After incubation for 48 h, cellular TG contents were measured. Data are means±SD from 3–5 experiments. Means without a common letter differ, p< 0.05.
